are they in a .zip file? if so extract the files before trying to edit them.

 

i cant do a single thing to them no they are not zip i think

 

With blender, you have to import it to blender

 

.jbeam, .cs, .pc and .json files can be opened with notepad or a similar program such as notepad++. .dds files can be opened with photoshop, paint.net or gimp (needs a plugin). And .dae files can be opened with blender or other 3D modeling software.
